The current tsens debugfs structure is composed by: - a tsens dir in debugfs with a version file - a directory for each tsens istance with sensors file to dump all the sensors value.
s/istance/instance/ The patch looks good to me, no need to resend, I'll fix the typos
This works on the assumption that we have the same version for each istance but this assumption seems fragile and with more than one tsens istance results in the version file not tracking each of them. A better approach is to just create a subdirectory for each tsens istance and put there version and sensors debugfs file. Using this new implementation results in less code since debugfs entry are created only on successful tsens probe.
